Hint: A wind vane is a device to measure the direction of the wind. The wind vane is generally combined with the anemometer. An anemometer is a device useful for measuring the wind speed and direction both. It is also used as a common weather station instrument.
Complete answer:
Main differences between Wind vane and anemometer are as follows:
Additional Information: Before the days of round-the-clock, forecasts about the weather were done with the help of wind and its speed and direction. Early farmers and sailors were looking at wind vanes to detect the wind direction and hence about the weather.
Note: Farmers and sailors are looking at the wind vanes for detecting the wind direction. They also use the anemometer to know about wind speed and pressure. The wind is having both speed and direction. Anemometers are used to measure the wind speed whereas the wind vanes measure the wind direction.
Complete answer:
Main differences between Wind vane and anemometer are as follows:
| Characteristics | Wind vane | Anemometer |
| Purpose | A wind vane is important to measure the wind direction. | An anemometer is important to measure the wind speed. |
| Components | Mostly these vanes are consisting of an arrow attached to a spindle. With the cross having four letters N (north), E (east), S (south), W (west). | Most anemometers consist of 3 or 4 spinning cups mounted on a shaft. |
| Structure | Electronic wind vanes are having a small magnet bar within it. It also consists of 4 reed switches. One is assigned to a specific direction. North being marked for the orientation through the compass. | These shafts are connected to a magnet and reed switch or the generator. |
| Existence of pointers | Typically a wind vane is having a pointer in front and fins in the back. When the wind is blowing then the wind vane points into the wind. | Nos such pointers. |
